Hope you are as (apparently!) successful as I was, Ryan. I'm fairly confident that the rear brake is now completely free from air, as it's showing no sign of sponginess after being stood for a week. We'll see whether exhaust heat affects it once I'm back on the road.

Good luck!

I must admit my 796 rear brake is probably the strongest rear brake I've ever had on a bike. I've not bled it or anything since owning the bike.
Both my previous MV's had shocking rear brakes from new and could barely hold the bike on a hill. They were bled ever year and always ended up being virtually useless. Strange.

Long may it continue!

Is yours ABS or non-ABS, Doggy? That might make a difference. The non-ABS model has a different, (and much shorter), hose routeing, which keeps it clear of both engine and exhaust heat. And, of course, there's no ABS unit in which to trap air or to complicate bleeding.

Don’t think I’ve touched my back brake other than hill starts since my master cylinder issues

Non ABS for me. A lot of the bleeding problems on mv number two were to do with the abs unit, so that makes sense.

Thanks Luddite,

Being impatient I've already ordered the very same version from an ebay seller who is undercutting the current price of your seller. The metal version of the pump looked very nice but it seemed silly to spend extra money on something I won't use that often, and only for brake/clutch bleeding. Then again, maybe I'll treat all the bikes to a quick fluid change!

Nick

My 1200s is the same, rear brake is very good. Not been touched since new.

Hopefully, by pushing the pistons back, raising the caliper, filling with DOT 5.1 and using the vacuum bleeder, I'll end up with a more permanent solution.

I shall report back in due course.
It's been over a year since I bled the rear brakes on the Evo so I thought it was about time I posted an update.

Well, all through last year, it worked perfectly although, admittedly, the bike didn't get used much so perhaps they weren't exposed to as much heat as other years. But, even after being laid up over winter for four months, (which is when, historically, the sponginess tended to reappear), I am happy to report that the pedal is still as firm as the day I bled them.

I think removing and raising the caliper above the ABS unit was probably the key element in this exercise. So, if your rear brake is soft after winter, try the above tips and you should notice an improvement.

That sounds like mine this time last year, Stu. I think you need a bleeding session this weekend. Take the caliper off and get it higher than the ABS pump and push the pistons right back into the caliper and you should be ok.

Thanks for the replies guy’s and nice to get a wee thread going. Guess everyone is keen on having good brakes

So if anybody is going to buy a mityvac, the mv8500 (comes with a case a some extra accessories is on ebay reduced to £63 from £87. Pretty good deal i reckon.

Bleeding awful……!

You could set yourself up as a Central Scotland bleeding contractor, James, recoup your Mityvac outlay in no time !
